Advances in nanomaterials-based chemiluminescence (bio)sensor for specific and sensitive determination of pathogenic bacteria

Foodborne pathogenic bacteria exist in different forms in foodstuffs and pose a great threat to public health. Therefore, the rapid and touchy orientation of bacterial pollutants in food is urgently required to prevent the spread and emergence of foodborne illnesses. Thanks to the superiority of simple construction, rapidness, brilliant sensitivity, and low interference, chemiluminescence (CL) has evolved into a dominant method for pathogenic bacteria exploration. Currently, nanomaterials like noble metal NPs, LDHs, MoS₂, MOFs, CDs, and QDs are broadly employed to intensify the CL radiation, because of their outstanding reactivity, unique photoelectric features, and wide surface area. Many encouraging advances have been made in bacterial analysis exploiting nanomaterial-based CL. However, a comprehensive review focused on the application of nanomaterial-based CL for tracing foodborne pathogenic bacterial analysis is still lacking. Thereinto, the current progress of nanomaterial-based CL towards representative harmful pathogenic bacteria has been accentuated, comprising Salmonella spp., Staphylococcus aureus (S. aureus), Bacillus cereus, Listeria monocytogenes (L. monocytogenes), Escherichia spp. Ultimately, we presented our predictions and thinking on exploring novel nanomaterial-based CL scaffolds.
